BOTTLE-CLOSURE.

SPECIFICATION forming part of Letters Patent No. 576,417, dated February 2, 1897;

` Application filed J'u11e14, 1895. Serial No. 552,842. (No model.)

Vpurity of the contents and delivering the last drop as fresh and sparkling as when first put in. I obtain this by the arrangement of parts hereinafter set forth and claimed, reference being had to the accompanying drawings, forming part of this specification, similar letters of reference indicating corresponding Vparts of the several figures.

Figure l is a vertical sectional View through the center of the closure and nozzle of a bottle to which the closure is attached. Fig. 2 is a plan view of the closure, taken on line q q of Fig. 1. Fig. 3 is a perspective view of the cylinder B, showing Vthe lugs j j. Fig. 4 is a view of the upper part of the closure, showing the inclines it" and stops nn upon its upper surface.

Referring to Fig. l, the body of the closure is cylindrical, having three compartments, thelower one, c, being threaded to form a screw-fitting properly-constructed threads on the nozzle of the bottle. The diaphragm d separates the upper compartment a of the body A from the middle compartment o?.

B is a hollow cylinder (shown in detail in Fig. 3) which moves telescopically in the upper division a', having a cap or thumb-piece c fixed on its upper-end. Upon the outside of the cylinder B and opposite each other are lugs jj', said lugs jj extending downward from said cap c about two-thirds the length of said cylinderB, the remainder of said cylinder being used to give steadiness to its movement within said chamber d. The middle chamber a2 is between the upper diaphragm d and the lower one, f, to which chamber is connected the nozzle O. Diaphragm f also forms the valve-seat s of the valvec. Lu gs jj move in corresponding grooves g g', said grooves being formed on the inside surface of the upper compartment a. These grooves extend downward the full length of the lugs jj and should be in line with the nozzle O. inclines t z" are of equal length formed on the top edge of the body of the closure, (shown more fully in Fig. 4,) and should be inclined at an angle of about five degrees, having shoulders n n at the lowest points. Said shoulders form stops for lugs jj when rotating the cylinderB, enabling the operator to readily find the grooves g g. The valve-rod p is attached to cap c and passes downward through the diaphragms cl and f, and should be of suflicient length below diaphragm f to attach thereto the valve c, nut m, and spiral spring which surrounds the rod p. The nut m supports said spring x below the shoulder r. The valve fu is so constructed as to allow the rod p to move freely through it. The spring x is used to counteract the effect of spring t, which encircles the rod p in said cylinder B and to force the valve o back to its seat when the valve has been opened to draw the contents of the bottle. Spring t rests on a gasket o and extends to the under side of cap c. The lengths of these springs rr, and t depend on the length of the closure and must be adapted thereto. l

r2 is a gasket placed between the bearingsurfaces of the nozzle of the bottle and the closure A.

In operating the locking device the lugs j jare raised out of the grooves g g by the cap c and the cylinder B turned to the right, which forces the lugs j j on the inclines e' z", thereby locking the valve o on its seat. The cylinder B, and consequently the rod p, cannot be depressed while the lugs jj are on the inclines t' i. To unlock the valve 'u for the purpose of drawing the contents of the bottle, turn the cylinder B backward or to the left until lugs jj/ reach the lowest points of the inclines t' e, where they are stopped by the shoulders n n and intersect and fall into grooves g g.

I am aware that bottle-closures secured to the nozzles of bottles by means of threaded rims have been made prior to my invention, and I do not claim the same; but

What I do claim, and desire to secure by Letters Patent of the United States, is

l. In a bottle-closure the combination of a IOO cap provided With a diaphragm Closing the mouth of the bottle, said diaphragm being provided With an aperture, a reoeption-ohamber above the diaphragm, which is provided With an opening for pouring the liquid out and a valve for closing the aperture in the diaphragm mounted upon a rod which is provided with a spring for seating the valve and a looking device upon its upper end to lock the valve upon its seat.

2. In a bottle-Closure the combination of a cap provided with a diaphragm closing the mouth of the bottle said diaphragm being provided With an aperture, a reception-Chamber abover the diaphragm, which is provided with an opening for pouring the liquid out and a valve for closing the aperture in the diaphragm mounted upon a rod Whioh is provided With a spring for seating the valve and having a thumb-piece secured to the top of ber above the diaphragm which is provided with an opening for pouring the liquid out, a valve for closing the aperture in the diaphragm mounted loosely upon a rod and having a spring belowr it surrounding the rod and pressing the valve upward and a looking device upon the upper end of the closure to look the valve upon its seat.
